Emasculatome



Patented Get. 10, 1933 UNITED STATES PATENT: OFFICE This invention relates to emasculatomes and has for one of its objects to produce a device of this character of strong durable, efficient and inexpensive construction, possessing suflicient power to effectually break, crush or so mutilate the spermatic cord and its blood supply so that, in a short time, atrophism is effected which results in the emasculation of the animal.

One of the objects of the invention is to produce a device of the character set forth which applies a rolling, as distinguished from a sliding or abrasive, force upon the portion of the scrotum so that there is no material breaking of the skin which is objectionable since it offers a point for 5 the entry of infection.

Another object of the invention is to produce a construction which can be readily manipulated by a single operator, the clamping or pinching jaws being so made that in their initial closing movement the first action is to catch or entrap the flesh so that as the pressure thereon is gradually increased, there will be no opportunity or chance for the parts to slip from between the jaws.

A still further object of the invention is to produce a device of the character described which is small and. easily operated and may be readily dismantled for transportation, and which may be used on either a standing or a prone beast.

to produce a device for the emasculation of animals, it is to be understood that it may be employed for analogous or similar operations on animals, for example, it is efiective in the docking of sheep.

With the general objects named in view, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is tobe had to theaccompanying drawing, in which:

Figure l is a view showing the device with the jaws in open position.

Figure 2 is a view showing the device in fully closed position.

Figure 3 is enlarged view, partly broken away to disclose parts otherwise hidden.

Figure 4 is a section on the line IVIV of Figure 3.

Figure 5 is a section on the line V-V of Figure 3.

Figure 6 is a view of the jaws as they will ap-- pear in a partially closed relation incident to the entrapment of the part to be operated upon.'

Although the chief object of the invention is' In the said drawing, where like reference characters identify corresponding parts in all of the figures, 1 indicates a housing or casing formed with a pair of tubular journal or hearing bores in which are rotatably mounted a pair of cylindrical members 2, each of said members 2 having a threaded socket for thereception of the threaded end of an operating handie 3, projecting outwardly through their respective slots 4, formedin the casing 1, said slots limiting the opening and closing movements of the handles 3. It will be evident that with the parts as thus assembled, the handles 3 will prevent their respective members 2 from moving in either direction out of the'casing 1.

At one of their ends, the axially rotatable members 2 are equipped with intermeshed gears 5 so that movement of said members shall always be synchronous, for a purpose which will hereinafter appear, and'in order to keep dust and dirt from gaining access to said gears and at the same time to provide a lubricant containing chamber, the end of the casing 1 is equipped with a removable cap or cover 6.

The housing or casing 1 may also be provided so with a fixed handle 7 for convenience in the handling or manipulation of the device. Although the handle 7 is not essential, it will be found convenient, particularly when a single operator is handling the device inasmuch as he may, while maintaining the animal parts between the clamping jaws as hereinafter described, utilize the handle 7 as an abutment while he grasps one of the handles 3 to start the jawclosing operation, and said handle 7 will also form a fixed abutment or stop to limit closing movements of the handle 3, as shown in Figure 2, for relieving their threaded ends of excessive strain.

The members 2 at their ends opposite the gears 5 project from the casing 1 to form a pair of cooperating clamping jaws 8, said clamping jaws being formed by cutting away the cylinders 2 so that when the device is fully open the jaws form opposed spaced plane or flat" surfaces between 00 which the animal part or other thing to be operated upon may be inserted.

Along one of their side edges, each jaw 8 is formed with a projecting rounded bead 9, which forms a curved crushing surface in plan view, see Figures 3 and 6, whereby upon the closing movement thereof through axial rotation of members 2, the ends or extremities of the jaws, formed by the curved surfaces or beads 9 will come together or approach each other quicker 119 than the other portions of the beads or crushing surfaces of the jaws. Thus the initial movement of the jaws effects the entrapping of the part being operated upon, the casing 1 forming an abutment at one end, and the extremities or tips of the beads 9, a closure at the other end, to prevent such part from slipping from between the jaws upon the application of clamping pres sure to break or crush such part.

Operation While the jaws 8 of the device are in open position with their plane surfaces in opposition, as shown in Figure 1, the animal part to be crushed is threaded between them, either while the operator holds the device by means if the handles 3, the casing 1 or the auxiliary handle 7. If one man is performing the operation, he will usually maintain the part between the jaws with one hand, while, with the other hand and fingers, he will start the closing movement of the jaws through manipulation of the handles 3, with or without the cooperation of the handle 7, as found most convenient. As heretofore stated, the beads or surfaces 9 of the jaws 8 are'so curved that their free ends or extremities rapidly approach, as shown in Figure 6, to entrap or catch the part to be crushed by lessening the space or opening at the free ends of such jaws. As soon as this has occurred, the operator may utilize both hands :to operate the jaws to effect full closing movement with the consequent breaking or rupture of the cord or other part through pressure applied thereon by the beads 9. It will be evident that as the'jaws axially rotate, the resultant force applied, is in effect a simultaneoussqueezing or compression and a rolling action, whereby abrasive or scraping of the flesh is to a large extent avoided with the result that there is no material breaking of the flesh orskin.

From the above description, it will be apparent that I have produced'a device possessing all of the advantages set forth as desirable, and while I have described and illustrated the preferred embodiment of the invention, it is to be understood that I reserve the right to make all changes within the spirit of the invention and without the ambit of the prior art.

1. A device comprising a'pair of axially rotatable jaws arranged to progressively approach or recede throughout their range of movement through axial rotation, said jaws being adapted to effect the crushing of animal parts, and manually operable means for effecting the operation of said jaws. I

2. A device comprising a portable housing, a pair of jaws carried by and projecting from said housing and being adapted to open to receive an animal part to be crushed and to close to effect crushing of such part, a handle projecting from said housing and manually operablemeans for effecting operation of said jaws, said means and handle being adapted for cooperative use in the commencement of the jaw-operating movement.

3. A device comprising a pair of axially rotatable jaws arranged to progressively approach or recede throughout their range of movement through axial rotation, said jaws being adapted to effect the crushing of animal parts, a connection between the jaws to insure synchronous operation thereof, and manually operable means for effecting operation of the jaws.

5. A device of the character described comprising a pair of jaws for approaching andreceding movement, an abutment at one end of said jaws to prevent movement of material from between the jaws, said jaws being of curved form whereby the first movement thereof effects the approach of their ends remote from the abutment, and manually operable means for effecting operation of the jaws.

6. A device comprising a portable housing, a pair' of jaws carried by and projecting from the housing and being adapted to open to receive an animal part to be crushed and to close to effect crushing of'such part, a housing handle projecting from the housing and an operating handle for each of said jaws projecting from the housing, said housing handle and either of said operating handles being adapted for cooperative use in the commencement of the jaw-operating movement.
